Storm sash ventilator



Oct. 3, 1933. A. T. WILSON STORM SASH VENTILATOR Filed April 9, 1932 Patented Oct. 3, 1933 UNITED STATES STORM SASH VENTILATOR Andrew T. Wilson, St. Boniface, Manitoba,

Canada Application April 9, 1932, Serial No. 604,198, and in Canada March 31, 1932 2 Claims.

The invention relates to improvements in storm sash ventilators and an object of the invention is to provide a ventilator construction which allows the ventilator to be very easily shifted from closed to open position or the reverse and without any possibility of jamming as at present so frequently occurs with ventilators on the market and a further object is to provide a ventilator which can be positively fastened in any adjusted position to insure that there will be no undesirable rattling.

A further object is to provide a construction which givesthe above advantages and without departing from regular sash construction practice.

A further object is to provide a ventilator construction which can be applied on existing storm sashes without altering the same and the complete device being particularly simple, durable and inexpensive.

With the above more important objects in view. the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawing, in which:-

Fig. 1 is a front view of a sash equipped with my invention.

Fig. 2 is an enlarged detailed front view of a ventilator and associated parts.

Fig. 3 is a horizontal sectional view Figure 2.

Fig. 4 is a vertical sectional view at 4-4 ,Figure 2 and looking in the direction of the applied arrow.

Fig. 5 is a sectional view similar to Figure 4 showing a slight modification in the structure.

In the drawing like-characters of reference indicate corresponding parts in the several figures. The storm sash 1 herein shown is of the usual type and has the four relatively large lights or window panes 2, a small window pane or light 3 at the bottom and a ventilating opening 4 at the bottom. This opening is rectangular and is of the same size as the opening in the opposite side of the window which receives the pane of glass 3. Usually the ventilating opening is closed by sliding ventilator which has its lower edge slidably received in a suitable channel provided in the bottom rail 5 of the sash and its upper edge slidably received in a similar channel associated with the sash bar 6. My experience has been that such types of channel guided ventilators do not always slide freely and it will'be obvious that the freer they are to slide the more possibility there is of rattling which is undesirable.

Accordingto my invention, the ventilator "I which embodies alight or glass pane 8 in a suitable rectangular frame 9, is provided at its upper comers with similar strap hangers l0 and 11 screwed to the ventilator and slidably mounted on a horizontally disposed carrying rod 12 which is attached to the sash by three hangers 13, 14 v and 15. It will be observed that the straps provide eyes to receive the rod, the eyes of the straps 13, 14 and 15 being firmly jammed or fastened to the rod while the eyes of the straps l0 and 11 are slidably mounted on the rod. The straps 13 and 15 are fastened to the stiles of the sash and the strap 14 is fastened to the vertical central bar 16 of the sash which latter passes between the bottom and top rails of the sash.

The ventilator is of such a size that it will close the opening 4 in the closed position thereof and obviously one can open the ventilator to a greater or less extent by sliding it endways on the rod and there is no possibility of it jamming.

A finger grip or handle 17 is provided centrally of the ventilator at the bottom so that it can be easily manipulated. To the bottom rail of the sash, I connect pivotally a pair of similar buttons 18 and 19 which are utilized to hold the ventilator tightly against the sash in any position thereof. Each button embodies a head 20 and an extendinglever arm 21 in the form of a finger piece and it is fastened pivotally to the sash by a screw 22, suitable inner and outer washers being provided.

In the principal views of the drawing the sash is shown as provided with a central vertical bar 16 and the central hanger 14 is screwed to this bar. Sashes, however, are very often made with two main lights and there would then be no central bar 16. In such a case, the central hanger 14 would be fastened by screws to the sash bar 6 in the manner shown in Figure 5.

The construction provided is readily adaptable to various types of storm sashes and obviously can be very cheaply manufactured and applied and supplies a ventilator which can be most easily shifted and when shifted can be fastened to prevent rattling.

What I claim as my invention is:-

1. The combination with a storm sash provided with a ventilating opening, of a ventilator normally closing the ventilating opening, a guide rod crossing the sash above the opening and permanently carried by the sash and hangers pivotally swung from and endwise slidable on the rod and permanently secured to the ventilator.

2. The combination with a storm sash provided with a ventilating opening, of a ventilator normally closing the ventilating opening, a guide rod crossing the sash above the opening and permanently carried by the sash, hangers pivotally swung from and endwise slidable on the rod and permanently secured to the ventilator and means carried by the sash and releasably ensageable with the ventilator to prevent inswinging of the ventilator.
